UNITED STATES NICHOLAS SHELLABARGER, OF PORTLAND, OREGON AMUSEMENTnnvrcn.

Application filed August 28, 1926. Serial No. 132,187.

The primary object of my device is to provide an amusement device foruse in play grounds, at the home and school and all places whereamusements are provided for children, in a form that may be used in amultiplicity of ways, as a merry-go-round, operating about a horizontalsupporting member and wherein the occupants may be made to entirelycomplete a circular rotation about ahorizontal support.

A further object of my new and improved amusement device consists inproviding simple and eflicient means for transforming my device into aplain swing, or into a teeter board or a combination of the twomovementsof a see saw movement as well as a movement up and down. Simple meansbeing provided for adjusting the supportlng members'to compensate in thedifference in weight of the users of the device.

A still further object of my device consists in providing means forstoppmg the supporting member at predetermined polnts and maintainingthe same in a relatively stationary condition.

A still further object of my device consists in providing standards ofsupport for the different members that may be easily erected and takendown to make the same portable in effect.

A still further object of my device consists in providing means thatwill bring the supporting member to a position of rest at the same'placeat all times and that will maintain the same in a position of rest untilreleased from locked position. 7

A still further object of my device is to provide a simple amusementdevice that will give a variety of amusements and yet be simplyconstructed and that w1ll contlnue to operate over long periods wthoutexpensive repairs.

With these and incidental objects in vlew, the invention consists incertain novel features, the essential elements of which are set forth inthe appended claims, and a preferred form of embodiment is hereinaftershown with reference to the drawings which accompany, and form a part ofthis specification.

In the drawings Fig. 1 is a side elevation of the assembled device withthe seats and the supportin side rails therefor illustrated in horizontaposition.

Fig. 2 is a top plan view taken on line 2--2 of Fig. 1, looking in thedirection indicated.

Fig. 3 .is a front view'of the seat support taken on line 3-3 of Fig. 2,looking in the direction indicated.

Fig. 4 is a side elevation of the device with the supporting side railmembers and the seats secured thereto in position for use as a teeterboard.

Fig. 5 is an end view of thedevice with the side rails positioned foruse as a swing, with one of the seats removed from the supporting rails.1

Fig. 6 is an end view of the frame structure illustrating the framedmembers being used as'supports for rings.

Fig. 7 is an end view illustrating the frame structure in position andused as a support for a tumbling bar.

Like reference characters refer to like parts throughout the severalviews.

I make my frame structure preferablyof pipe material the side members ofwhich are made in the form of an A-frame, having two legs, 1 and '2,disposed on either side thereof, meeting at a common point 3. Thestructural member 5 is formed of a' rigid material and is adapted toreceive the leg members 1 and 2 in sockets formed therein; and having avertical standard 4 disposed on the upper side thereof. The

side frames are held in spaced relationship Disposed midway of the crossbar 6 is a j'ournaled bearing 9.

When the dBVlCGlS intended and erected for use as a merry-go-round, twoside members, 10 and 11, are journaled about the shaft 12 that issupported on either end within the structural member 5. J ournaledbearings 13 and 14: being secured to the side rails 10 and 11, and thecross bar 12 is journaled therein. This permits of a free rotation ofthe side rails 10 and 11 about the shaft 12. Seats 15 and 16 arepositioned at either end of the side rails and are supported in positionby yokes 17 and 18. The yokes 17 and 18 are journaled within bearings 19and 20. The bearings 19 and 20, for supporting the yokes and the seatmembers, are in slidable relationship with the side rails and may bemaintained in fixed position by the set screws 21 and 22. Thiscompensating movement of the seat supporting bearings and yokes isnecessary to provide means for compensating for a difference in weightof the users of the device. A brake drum 23 'is maintained in fixedposition with the side supporting frame members and has imposed aboutthe outer periphery thereof a brake band 24. A spring 25 normallymaintains the brake band in tight relationship with the brake. drum, butthe same may be released by pulling the brake rod 26, thus flexing thespring 25 and releasing the band from the drum. To maintain the brakeband in released position from the drum the rod 26 carries a ring 27which may be made to engagestop pin 28,. disposed in one of the siderail-members.

A safety bar 29 is hinged about a pin 30,

associated with a bracket disposed in one,

side. of the seat members. The swinging end of thesafetybar 29 may bemade to engage latch bar 31, and be maintained in position by'the-string82.

VVhenit is desired to use one of my new and improved devices for ateeter board, the cross shaft 12; isdisposed Within-the journal bearing9, and as this shaft supports the side rail members 10 and 11, by meansof the journals 13 and 14, a partial rotation is secured between theshaft and the bearings to forma teeter board of the side rail members.The seat members being used as heretofore described. Should it bedesired to use one of my amusement devices in supporting a pair ofrings, the side. railmembers-are removed from the frame structuretogether withtheseats and the cross shaft. 12 at which time'the rings3.4;, together with their supporting members 36. and 37, are supportedupon theirv cross shaft 35.

My device can also beused as a pendulumswing by removing the cross shaft12 from the support members 5, and thebearings-l3 and; 14. Then one ofthe. seats and its supporting yoke is removed. from its bearing and theshaft inserted instead, this positions the cross shaft 12 at one end ofthe side mem bers l0 and 11, the cross shaft is then supto accomplishthe objects primarily stated, it

is not intended to confine the invention to the specificform. herein.described, as 1t 1s sus- .ceptibie of embodiment in various limited waysall. coming within the claims which follow..

-What I claim is g 1,111. a device of the class described, thecombination with supporting members provided with means for supporting across shaft at optional heights, and a cross shaft, of a. pair ofparallel spaced members bearings at the opposite. ends of said members,removable seats pivotally carried. by said bearings, other bearingsintermediate the ends of said members rotatably supporting said membersto said shaft to form a revolving swing; and means permittingsaid lastmentioned bearings to be removed from said shaft and the bearingssupporting one scope of' the of the seats substitutedv to form. apendulum" Swing.
